Ordis Solarius Articulum Kapacitusbankus Abampere Quinquaginta OSAKA50
I received a "Animaris Ordis Parvus" leg kit from our friends at Gakken ....
.... as a Bonus for sending my SchneeBeast for a Theo Jansen exhibition in Japan.
The original kit was powered by the wind and indeed it drives forwards in the lightest of breezes. (as proved by rik)
However it was calling out for a bit more power so what i present here is Solar powered version.
The basic idea was to split the beest in half and drive both sides independently.
With this configuration it can be set up to find and follow the sun.
Driving the motors calls for a "Burst Mode" technique in the form of a Miller Solar Engine.
The Miller Solar Engine basically charges up a capacitor bank (6 x 3300uF in my case) from the solar cells.
After a predetermined voltage ..... all the power stored in the capacitor bank is transferred into the motor via a drive transistor..
This means that a much more powerful jolt can be supplied giving more power and torque, the plus factor is that it also gives OSAKA a very organic movement.
The Gakken magazine in question can be found here....
And Non Stream Videos can be found here.... yes all 8 of them :-
